Review: Bolt on ! Se change en l'espace de 15 min et es extrêmement puissance jai éclater mes pneu dboots a la première utilisation sur mon granite Wow !
Review: habe das Upgrade bis jetzt dreimal getestet funktioniert ordentlich einfache Umrüstung, einfache Einbau. Das wichtigste ist jedoch, dass man einen separaten Receiver erwerben muss, da man sonst das Auto nicht fahren kann. Dieser kostet noch mal zwischen 20 und 50 €.

*by A***O on 8 December 2025*

Pretty amazing upgrade for an older brushed Senton beginners truck. Was very easy to install and speeds are insane with the 3s battery. Works very well with 2s 5000 if you want better lower speed control
